The ADF4001BRUZ-R7 is an Integrated Frequency Synthesizer designed for cellular basestations. It leverages a PLL and produces a very low power and minimal area solution due to its on-chip reference crystal, integer-N divider, and excellen low current consumption. The ADF4001BRUZ-R7’s design facilitates distribution-based operation, eliminating the need for an external reference and multiplexer, providing improved system scalability for designers desiring to support multiple basestations. The ADF4001BRUZ-R7 is designed to support legacy transceivers and cellular basestations, along with the next-generation of cellular technology such as TDD-LTE and TD-SCDMA.

The ADF4001BRUZ-R7 supports a wide range of applications that require a standard frequency synthesizer. It supports frequencies ranging up to 2000 MHz, with a phase-noise of -80 dBc/Hz at 1-MHz offset. The ADF4001BRUZ-R7 has excellent phase noise performance, and can support both narrowband and wideband systems. Additionally, it has an on-chip LPF filter, which reduces jitter and improves output signal purity. The integrated voltage-controlled crystal oscillator (VCXO) also further improves jitter performance, ensuring reliable signal reception and transmission.

The ADF4001BRUZ-R7 utilizes a fully integrated Crystal Oscillator (XO) for external reference and a very low power PLL, which can be used to generate frequencies up to 2000MHz. It has a low jitter reference input with good phase noise performance and a wide operating temperature range. The ADF4001BRUZ-R7 also has an excellent jitter injection mechanism, built-in frequency multiplication circuitry, and an integrator and charge pump to optimize loop gain control.

The ADF4001BRUZ-R7 features an on-chip reference crystal that allows the Synthesizer to run even when the external reference is lost. This eliminates the need for a separate, memory-mapped reference input and allows the synthesizer to operate even when the external reference is lost. Additionally, the wide operating temperature range and excellent jitter performance of the ADF4001BRUZ-R7 enable reliable signal transmission and reception.

The ADF4001BRUZ-R7 can be used in a variety of applications such as cellular basestations, satellite communication, point-to-point communication, and wired communication. The device can be configured for local oscillator (LO) or stabilized oscillator (STO) applications, and it can also be used in communications applications that require frequency hopping. In addition, the frequency synthesizer is ideal for distributed antenna systems (DAS) to enable communications in challenging environments.

In summary, the ADF4001BRUZ-R7 is a low power, low area frequency synthesizer designed for cellular basestations. It has an excellent wide temperature range, low power consumption, and a highly integratable feature set for efficient design and scalability. The device also has an excellent jitter injection mechanism, as well as an on-chip VCXO, which provides reliable signal reception and transmission for various applications. This device is highly recommended for those who require a synthesizer for their basestations and other applications requiring frequency synthesis.
